Application filed April To aZZ whom it may comer-n:

Be it known that we, Jose-r1: L. Bonny and Bonnie FnL'rs, citizens ofthe Uni ed States, residing at King City, in the county of Gentry, Statea new and useful l'riissouri, have invented n r (j 1' an r" ningme-00am, an, and

we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to cooling fans for internal combustion enginesand has for its object to provide a fan of this character, which iscarried by a casing and is driven through the medium of gearing and ashaft y from the crank shaft thereby providing a positive drive and acooling fan which may be easily applied to an engine, and removedtherefrom if so desired during cold weather.

providing a positive gear and shaft drive nt to Le driving of the fan bya belt which is a A further object is to provide a cooling fan forinternal combustion engines and a drive for the same comprising aecasingwhich may be secured to the engine casing, said casing having rotatablymounted in bearings thereof a shaft, which shaft has gear connections tothe engine drive siiaft and with the fan shaft.

lVith the above and other objects in view the invention resides in thecombination and arrangement of parts as herelnafter'set forth,

shown in the drawings,

described and claimed, it being understood that changes in the pre be lise embodiment the invention may within the scope of what is claimed,

without departing from the spirit of the invention.

ment by means of an adjusting screw 1921' Serial N0. 371,595.

which screw lock nuts 8 are threaded so that the screw 7 may be lockedand held in any position to which it may have been moved. he upper endof the casing is provided with an opening 9, which opening is of slighlv reator diameter than the worms 10 carried by the shaft 6, theincreased diamter of the opening 9 when the bushing 11 is removedallowing the shaft 6 and its worms 10 to be placed in or removed fromthe chamber of the casing 4 as desired.

Secured to the sides of the casing l are casings 12, in bearings ofwhich casings, a shaft 13 is rotatably mounted, on which shaftconventional form of fan 14 is secured. The chambers 15 of the casings12 are in communication with the chamber of the casing 4 sothat'lubricant which may be placed in the casing 4- may also fill thechain bore 15. The chambers 15 also form pockets for the reception ofworm gears 16 and 17. The worm gear 16 being keyed or otherwise securedto the fan shaft 15 and meshing with the upper worm 10, carried by theshaft 6, while the worm gear 17 may be keyed or otherwise secured to thedrive shaft 2 of the engine and in mesh with the lower worm 10 of theshaft 6.

it will be seen that as the shaft 2 rotates that the shaft 6 will alsorotate for the reason that the worm gear 17 is in mesh with the worm 10at the lower end of the shaft 6. Shaft 6 will cause the fan shaft 13 torotate through the medium of the upper worm 10, which meshes with theworm gear 16-carried by the fan shaft, therefore it will be seen that apositive drive for the fan is provided which drive eliminates the use ofthe common fan belt now in use which becomes worn, slips and at timesbreak. it will also be seen that to remove the fan from the engine itwill only be necessary to disconnect the brackets 3, then remove thecasing 12.

The invention having been set forth what is claimed as new and useful isA cooling fan being provided with a horizontally disposed shaft, saidshaft rotatably mounted in bearings of a segmentally shaped casing, arotatable shaft rotatably mounted in a second segmentally shaped casing,a vertically disposed shaft rotatably mounted in bearings of avertically disposed casing, the rotatable shafts carried by the segment-.ally shaped casings and provided withgear 10 posed shaft thereby ing,anti-frictional means for supporting the ends of the vertically disposedshaft adjusting means cooperating with one end of a vertically disposedshaft and forming means whereby Wear may be taken up, the upperanti-frictional hearing being disposed in an opening in the casing; ofgreater size than the gears carried by the vertically disallowing shaftand
